Hi I'm currently 12dpo , I've had light pink/brown spotting for 3/4 days . I've had a few early pregnancy symptoms such as lower back ache, frequent urination, dizzy spells , heightened smell and nausea . I took a pregnancy test yesterday afternoon as I couldn't wait however this came back negative . My period isn't due until Sunday . Is there still a chance I could be pregnant , and have I tested too early ? I now today have a increase in clear discharge which isn't my usual amount . Is this normal ?
